I asked my lecky to install 3 Dimplex Quantum 150 storage heaters in my 3 storey town house (one per floor) plus a Dimplex QRAD 150 panel heater in our baby's room. I'm wondering whether there's any way to avoid forking out an extra 600 quid for the additional circuit on the top floor he suggests below. When he calculated the load it may have been on the basis of us already having a 1kw Nobo panel heater in our master bedroom (at the front part of the house), but we don't actually need to use this. I'm thinking perhaps he could connect the QRAD 150 to the rear socket circuit and use the circuit in our bedroom at the front (currently supplying the 1kw panel heater) for the top floor QM150's 'on-peak' supply.
Thanks very much in advance for any suggestions. Tech specs for the quantum and qrad are on Dimplex's website (sorry I'm not allowed to post links).
[SIZE=medium]"I have looked at the circuits in your home and have some concerns about the amount of power required for the additional heating load. There are three circuits which would be used for the additional load from these heaters due to their current positions in the property. I am satisfied with the additional load for the heaters towards the front of the house, but there are two heaters (top landing and rear bedroom) which are closest to the rear socket circuit. This is supplying the kitchen and is currently protected by a 16A circuit breaker. As an example, a kettle or toaster will each draw about 10A. A circuit breaer will allow an overload to pass through for a period of time, as the cables will not be damaged by a slight overload for a short period of time. The additional heaters have a current rating of about 12A. To add this to the current circuit will create a design overload that is likely to cause the circuit breaker to operate. It is also likely to increase the rate of ageing of the circuit.[/SIZE]
[SIZE=medium]A solution would be to take an additional circuit up to the first floor. If I remember correctly, it is possible to run a cable through voids from the airing cupboard to the garage. This will provide sufficient capacity to run the heaters on the top floor without detrement to the existing installation. Please confirm that this proposed cable route is possible. I have prepared our quotation on the basis of installing an additional circuit using this cable route."[/SIZE]
